Prioritize port/airport proximity, WMS functionality and API capabilities, peak‑season scalability, SLA for pick & pack and returns, and multi‑carrier last‑mile integrations. Evaluate throughput, slotting strategies, and cross‑dock capacity to match order profiles and seasonality.

Feeder frequency and airlift determine transit windows and inventory buffer needs. Regular feeder lines reduce ocean transit variability; reliable air connections shorten lead times. Align reorder points and safety stock to scheduled sailings/flight rotations to minimize expedited freight.

Consider regional tax regimes and special economic zones that can reduce duties and operating costs, lower labor rates relative to some mainland hubs, and potential customs simplifications for reexports. Factor handling tariffs, free zone eligibility, and warehousing incentives into landed cost models.

Look for real‑time WMS with API/EDI, carrier connectivity for label generation and tracking, omnichannel inventory visibility, returns management workflows, and reporting/BI. Confirm integration roadmaps and support for your ERP or eCommerce platforms.

Request historical performance metrics for on‑time delivery across islands, peak throughput figures, contingency plans, and examples of handling seasonal surges. Review network partnerships, local carrier agreements, and cross‑dock capabilities that reduce dwell and expedite island deliveries.
